Solution Overview

Problem

In existing photographing methods, the composition can only be determined by the photographer, leading to unsatisfactory photos for the photographed person, as they cannot see the composition mode or photographing effect in real time.

Innovation Solution

A mobile terminal with dual displays is used, where a preview image is shown on one screen and composition reference information is displayed on the other, allowing the photographed person to select and adjust their position according to the composition information in real time before taking the photo.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If the photographer determines the composition using traditional methods, then the photographing process is simple, but the photographed person cannot see the composition mode or photographing effect in real time and may be unsatisfied

Engineering Contradiction:
ImproveReal-time composition information visibilityVSAvoidDisplay system complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent introduces a second display screen that provides a third-dimensional viewing angle for the photographed person. This additional display dimension allows simultaneous presentation of preview images and composition reference information to different users (photographer and photographed person), resolving the information asymmetry without significantly increasing overall system complexity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The second display screen acts as an intermediary device that bridges the information gap between the photographer's view and the photographed person's needs. It mediates the composition process by displaying both the preview image and composition reference information, enabling the photographed person to understand and adjust their positioning in real time.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If composition reference information is displayed to the photographed person, then real-time adjustment and satisfaction are improved, but the device complexity increases

Engineering Contradiction:
ImproveReal-time composition adjustmentVSAvoidDual display system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The second display screen serves multiple functions: displaying preview images, showing composition reference information, and providing real-time feedback to the photographed person. This multi-functionality allows a single additional component to address multiple needs, improving ease of operation while minimizing the increase in device complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system enables the photographed person to independently view composition reference information and adjust their own positioning without requiring constant guidance from the photographer. This self-service capability simplifies the interaction process and reduces the operational burden on the photographer.

Inventive Principle:
Principle #25Self-service

3Loss of information

If traditional single display method is used, then device complexity is low, but the photographed person cannot preview the photographing effect and composition mode

Engineering Contradiction:
ImprovePhotographing effect previewVSAvoidDisplay configuration complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent introduces a second display screen that provides a third-dimensional viewing angle for the photographed person. This additional display dimension allows simultaneous presentation of preview images and composition reference information to different users (photographer and photographed person), resolving the information asymmetry without significantly increasing overall system complexity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

A photographing method and a mobile terminal are provided, which are related to communication technologies. The photographing method includes: receiving a photographing function start instruction; displaying, on the first display screen and the second display screen respectively in a full screen display manner, a preview image acquired by the rear camera; displaying, on the second display screen, pre-stored composition reference information; determining target composition information in the composition reference information; and controlling the rear camera to perform a photographing operation, based on the target composition information.
